I develop a plugin for QGIS. Before to integreted it in the QGIS I developped it with GIS library (Fiona, shapely, geopandas, ...) and it work well. Now I try to build it with plugin_builder of QGIS. The problem is I try to use my functions that I created with the previous libraries, but it seems like PyQGIS (QGIS) didn't recongnize them.
Is it possible to work with the GIS libraries to open, write a vector and make some processes in QGIS environment?
